Over the years, I visited the La Brea Tar Pits several times. It is one of the biggest Pleistocene fossil hotspots in the world. The La Brea Tar Pits are what is called a “predator trap”. Large herbivores such as mammoths, ground sloths, and wooly rhinos would get stuck in the tar. Their helplessness and cries of distress become a dinner bell for opportunistic predators such as saber-toothed cats, dire wolves, and short-faced bears. These carnivores would feast on the trapped herbivores until they themselves become stuck. These trapped predators then attract more predators to the tar pit. Finally, all these piled up corpses attract scavengers such as vultures, which also become stuck. This starts an endless cycle where predator and prey become stuck together in the tar, which created one of the biggest prehistoric mass graves in America. I am thinking of writing a scene in my dinosaur series where my fictional dinosaur species get caught in a similar predator trap.
